backstory( feel free to skip)

I work at a library, and i started a project to lock the catalog pc to only the library website and the catalog. Normally I'd leave it alone, but thw other computers have a time limit, and it's a bit unfair that someone could use that pc to just browse endlessly.

The Problem.

I used inercpl.cpl to nake a proxy serv and whitelist the library and catalog domains, but the search doesnt fully work.

Like if i search from the library homepage, then the search works, but if i search from the catalog results like in going to do a second search, then it doesnt work for some reason. Id have to go back to the home page or search from advanced to get it working.

Anyone familiar with this issue or how to address it? I tried looking through the website html and whitelisting the relevant domains in inetcpl.cpl, but still tge issue persists.
